If an object has a mass of 20 kg, what's the force of gravity acting on it on Earth?

A. 2.04 kg
B. 1.96 kg
C. 32.67 N
D. 196 N

Answer :

To determine the force of gravity acting on an object, we use the formula:

[tex]$$
F = m \times g
$$[/tex]

where:
- [tex]$m$[/tex] is the mass of the object,
- [tex]$g$[/tex] is the acceleration due to gravity (on Earth, approximately [tex]$9.8 \, \text{m/s}^2$[/tex]).

Given:
- [tex]$m = 20\,\text{kg}$[/tex]
- [tex]$g = 9.8\,\text{m/s}^2$[/tex]

Substitute these values into the formula:

[tex]$$
F = 20 \times 9.8 = 196\,\text{N}
$$[/tex]

Therefore, the force of gravity acting on the object is [tex]$196\,\text{N}$[/tex].

The best answer is:

D. 196 N
